In this episode we talk with Philippe Kruchten about architecture and software development processes like Rup and Agile. Philippe discusses what he calls the Elephants in the Agile room, and we also discuss his take on academic research on software engineering. We talk about cognitive biases and reasoning fallacies. Be sure to listen to the full episode - as Philippe explains: context is king! :)

This interview was recorded on the 13th of august 2012 at the Vrije Universiteit(VU) in Amsterdam.

We were lucky to catch software legend Alan Cooper on his visit to Amsterdam and talk with him at length about design and programming. Alan tells about how he created products like the first incarnation of Visual Basic, and we discuss some fundamentals of interaction design. We also talk about how design fits into the software development process.

Gamification expert Gabe Zichermann was in the Netherlands to give a talk at TheNextWeb conference in April. We managed to tackle him for an interview, and he put the Gamification hype into perspective for us with some compelling examples and a lot of theoretical background. We talk about user engagement as a metric, SAP as a gamification frontrunner (yes, SAP), behavioral economics and gamification as a silver bullet. Gabe finishes with a life lesson he got from playing a lot of Sid Meier's Civilization.

Weer eens een Nederlandstalige podcast dit keer, waarin we spreken met Jelmer Feenstra en Frank van Viegen, bedenkers en makers van de datingsite Paiq. Deze mannen hielden zich tijdens hun studie aan de Universiteit Twente al bezig met kunstmatige intelligentie en werken aan deze site die sinds 2005 is uitgegroeid tot een datingsite met meer dan 100.000 leden. In dit interview vertellen ze over de geschiedenis van Paiq. We praten over de techniek die ze gebruiken, verschillende features die ze hebben gerealiseerd en over het gebruik van kunstmatige intelligentie voor het matchen van leden van de site.

Dit interview is opgenomen op 14 maart 2011 Interview door @tjeerdhans en @freekl.Audio post-production door @Mendelt.

• Op hun blog posten de medewerkers van Paiq af en toe verhalen vanachter de schermen
• Paiq is in 2011 gekozen tot beste website van het jaar in de categorie dating sites
• Lees op Wikipedia meer over artificial intelligence en artificial neural networks

In this episode we talk with Kevlin Henney, an independent software development consultant and trainer from the United Kingdom, well-known from one of his books '97 Things Every Programmer Should Know'. In the interview we discuss a wide variety of subjects in software development, like the agile community, patterns, learning and languages.

Kevlin shares his thoughts on the software craftmanship movement and states his opinion on the discussion whether our profession is a form of engineering or not. In some parts of this discussion we refer to the Hot-or-Not presentation that Kevlin gave the night before the interview at Sioux, the Netherlands. You can find the slides of this presentation here.

The interview was recorded at the hotel 'la Sonnerie' in Son & Breugel. We would like to thank the hotel for their hospitality by providing the chapel as a recording room for the podcast.

Interview by @freekl en @arnetimAudio post-production by @mendelt

• Kevlin (co) authored two books of the Pattern-Oriented Software Architecture serie: volume 4 is a worked example of patterns for distributed computing and the 5th volume is a book on the concepts of patterns.
• In the podcast Kevlin refers to a famous quote of Jason Gorman: 'Software craftsmanship's not the "next big thing". It's an attempt to articulate what the "thing" always was'.
• Scrum can be seen as a 'Nomic' game, which is a game in which changing the rules is one of the rules.
• In a presentation called 'With Economy and Elegance - Software Engineering reclaimed' (slides here) Kevlin explains that Software Engineering is a form of engineering and a craft - following his claim there are no contradictions.
• Glenn Vandenburg explains what is wrong with the way Software Engineering is taught at universities in the presentation called 'Real Software Engineering' (video here).
• Software development is all about passion and fun. An example of passion is the Tenet of Professionalism from Uncle Bob: 'Work 40 hours for your employer and another 20 hours improving yourself'.
• A great example of fun and playfulness in our industry is 'the Globe', a piece of Ruby software which rotates itself.
• Another way to look at your code is with a tag cloud of all words used in a piece of software. This idea was proposed by Phillip Calçado.

In this episode we interview Dave Farley and Jez Humble about the content of their award-winning book on Continuous Delivery.

The basic premise of the book is that we need to move beyond Continoous Integration and occasional delivery and work towards practices that allow for the creation and deployment of final deliverables on all environments on every check-in. Jez and Dave explain the concepts behind the deployment pipeline and we discuss the practices and policies that come into play from the moment of check-in to updating the live version of software.

We talk about various strategies and patterns for testing, building and releasing software, and how these fit in with agile and lean software development.
